STOP-ACTlON FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 310,239, dated January 6, 1885.

Application tiled September 19, 1883.

To (U whom it may calmer/1 Be it known that I, hIORRIS S. Wnren'r, a citizen of the United States, residing at Vorcester, in the county of Vere-ester and State of Massachusetts, have invented certain new and useful Improvements in Stop-Actions for Organs;- and I declare the following to be a description of my said invention sufliciently full, clear, and exact to enable others skilled IO in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, which form apart of this specification.

In the drawings, Figure l is an end View of such parts of an organ-aetion as will illustrate the nature of my invention. Fig. 2 is a plan'view of the same. Fig. 3 is a sectional view of a stoppull with dot-ted lines to illus trate the positions of action. Fig. at is adia-' gram illustrating the action of the mute-connections. 5 is ariew of one of the mute connecting wires, and Fig. 6 shows the form and arrangement of the ends of the rockcrrods in connection with the pulls.

In a complete organ-action there are a greater number of stops than here shown, and it will. be understood that a greater or less number of such steps can be arranged in the series for operating in substantially the same manner as 0 herein described, some being connected for single action and others for combined action, according to the requirements of the instru ments; but as the arrangement of the individual devices are substantially similar for each of the mutcs,it will not be necessary to herein show and describe the entire organ-action.

The features of my invention consist in the construction and manner of arranging pull and rocker connections and the adaptation of the devices for operating one or more rocker rods by independent or combined action, as hereinafter explained.

In the reference to parts, A denotes the reedboard; 13, the brace, andO O the mutes,which parts may be respectively constructed and located in relation to the manual and sounding devices in any suitable or ordinary manner.

D, I), and 1) indicate stop-pulls, two of which are shown as adapted for operating separate mutes independently, whilethe other,

f, upon the top of the brace-board B, as illustratcd. The inner ends of the rocker-rods are turned upward, as at c, and respectively pass through slots (1 in the pulhbars D and D". They are then extended laterally, as at c, to the central pull, D, and are then turned downward to give engagement with offsets or lugs on the sides of said central pull. The sides of the pull-rod D are slabbed off, as indicated at d, and lug-pieces Z are attached at the rear end of the slabbedotl portion, to facilitate engagement ot' the pull with the ends of the rocker-rod wires at both right and left. The

outer ends of the rods E are bent at right angles or offset, as at E, to give the requisite swing or crank action for moving the mutes O. which latter are connected thereto by means of wires F, the ends of which are respectively hooked into slotted blocks 7, fixed on. the end So of the rockerarm FF, and to suitable arms or proiections on the mutes O, as illustrated. ltach rocker-rod arm 1]" and its connectingwire F are so arranged that the force exerted by the springs employed for closing the mutes, acting through the wire F, serves for retainin g the parts when the stops are drawn out and the mates are open,as well as for retaining them in place when the stops are not drawn. This action is illustrated in Fig. l, the full lines 0 showing the position when the stop is drawn or open, and the dotted line when the stop is closed. W'hen the connection is swung back as far as the dotted line 'w,the stop will move the remainder of the distance to close by the recoil ol'the springs on the mates. Upon the top of the pulls are arranged spring-wires l. carrying at their forward endslatch dogs or blocks i,which fall in front of the rocker-arms 0 when the pull is drawn forward, (see full line, Fi 3,) and serve for engaging with and swinging said arms backward with the back ward movement of the vdrawn pull. The spring I is made with an incline or bend at I, which rides up on the top edge of the back piece, I), with the extreme backward movement of the pull, thereby raising the dog '11 clear from the arm 6 of the rocker-rod, as shown by dotted lines,Fig. 3, leaving said arm free to be moved forward independent of the pull on which the respective spring and dog is located. The slabbed portion of the pull D and the slots (Z of the pulls D and D are of sufficient length to permit the arms 0 to swing forward independent of the movement of the pull. By this arrangement of parts the particular pulls D and D'- act on the rocker-rods when drawn each independently, while the pull D, when drawn, operates both of the rocker-rods simultane ously and without moving the pulls D and D", since thelatch-dogs on said pulls being raised permits the arms 0 to swing forward and back in the slots (l with the action of the pull D.

In any stop where it is not desired to combine the action the part of the wire rod 0 can be omitted, the arm 0 simply terminating at the top of the pull D.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the rocker-rod having an arm, 0, of the pull-bar provided with the spring I, having thcbcnd l. and latchdog 2", and the support-piece I), as and for the purpose set forth.

2. The combination ofthe rocking rods E15. provided with arms a and laterallyextended top portions (2, the pulls D D and the pull D, severally provided with springs I and dogs '13, all adapted l'or operation substantially as and for the purpose set forth.

\Vitness my hand this 27th day 01' August, A. D. 1883.
